Exhibit 26-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 1, 2016.  This system includes the surface water resources in the Carmel River Basin, the groundwater resources in the Carmel Valley Alluvial Aquifer and the Seaside Groundwater Basin.  Exhibit 26-A is for Water Year (WY) 2016 and focuses on four factors: rainfall, runoff, and storage.  The rainfall and Streamflow values are based on measurements in the upper Carmel River Basin at Sleepy Hollow Weir. 

 

Water Supply Status:  As shown, rainfall in September 2016 totaled 0.00 inches and brings the cumulative rainfall total for WY 2016 to 22.25 inches, which is 105% of the long-term average through September.  Estimated unimpaired runoff during September 2016 totaled 135 acre-feet (AF) and brings the cumulative runoff total for WY 2016 to 44,923 AF, which is 67% of the long-term average through September.  Usable storage, which includes surface and groundwater, was 27,960 or 95% of the long-term average at the end of September.  This storage equates to 74% of system capacity. 

 

Production Compliance:  Under State Water Resources Control Board (SWRCB) Cease and Desist Order No. 2009-0060, California American Water (Cal-Am) is allowed to produce no more than 9,703 AF of water from the Carmel River in WY 2016.  In addition, under the Seaside Basin Decision, Cal-Am is allowed to produce 2,251AF of water from the Coastal Subareas and 48 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2016.  Altogether, Cal-Am is currently allowed to produce 11,954 AF from Carmel River and Seaside Coastal sources for customers in its main Monterey system and 48 AF from the Laguna Seca Subarea for customers in Ryan Ranch, Hidden Hills, and Bishop Systems (not adjusted for Sand City Desalination).  For WY 2016 through September, Cal-Am has produced 9,577 AF from the Carmel River (including ASR and Table 13), and Seaside Basin.  This water production is 2,425 AF or 20.2 % less than the target specified for Cal-Am’s production from the MPWRS for WY 2016 to date.  Cal-Am has produced 9,648 AF for customer use through September.  A breakdown of Cal-Am’s production for WY 2016 is included as Exhibit 26-B.  For WY 2016 through September, 699 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 609 AF have been recovered for customer use and 137 AF have been diverted under Table 13.  Exhibit 26-C shows production breakdown from all sources for all uses.  Some of the values in this report may be revised in the future as Cal-Am finalizes their production values and monitoring data.
